1 Claim.

This invention relates to devices commonly applied to, and used with,watering hoses.

One of the objects of this invention is to provide a sprinklerwithquick-changing means between a Wider spray and a central singlestream Fig. 2 is a longitudinal midsectional view of the nozzle, openfor the central discharge.

Fig. 3 is a cross section on line 3-3 of Fig. 1. Fig. 4 is a crosssection on line 4-4 of Fig. 2. Fig. 5 is a longitudinal midsectionalView of a slightly modified form of nozzle. Fig. 6 is a fragmentary planView of the housing.

Fig. is a side viewof the housing .portion of ,-H; Fig. 6 as seen in thedirection of the arrow 'I'.

Fig. 8 is a fragmentary rear view of the removable clamping ring.`

Fig. 9 is a cross section on line 9*-9 of Fig. 8. As illustrated, therear end of the sprinkler nozzle is formed to screw and t on a hose,thisv portion being indicated at I0.

This portion It is provided with a cup-shaped extension II, which isprovided with distinct openings i2 and I3, one for feeding the wider t;spray, and another for feeding the central single stream discharge.

The sprinkler head is adjustably and turnably mounted on the cup-shapedextension I I and consisting of an outer housing I, an inner sleeve I5,z5 and an intermediate partition I6, all being firmly united so as toturn together on the cup-shaped extension II.

In other words, when the outer housing I is :75 this case being theopening I'I in the inner sleeve I5, to form the communication betweenthe inside of the cup-shaped extension II and the space formed by theinner sleeve I5y and the partition I B, whereby any water may reach the,central single stream discharge; and, for another thing, to feed by wayof the opening I2 and through another of these additional openings, inthis case being the opening I8, jointly in the inner sleeve l5 and thepartition I6, to form the communicav tion between the inside of thecup-shaped exm tension I I and the space formed by the partition and theouter housing I4, whereby any water may reach the wider spray cap I9when the united structure is turned so that the opening I8 comes intoalignment with the opening I2, as is thecaso i y, in the modified formof Fig. 5. I

From comparing Figs. 2 and 5 it is evidenty that a turning of the unitedstructure upon the cup-shaped extension in one direction gives a clearconnnunication for the central single spray; while, a turning in theopposite direction gives a clear communication for the Wider outersp-ray.

While the head is turned for the central single y discharge, this maystill be adjusted for a larger or less amount by means of the adjustingsleeve i 25" 2B, of which the innermost end 2l may be made to l seattightly upon the washer 22, so that, by a very ne opening, a ne spraymay evenv be had through the central discharge, though, by a fullopening of this sleeve 2), a larger rather solid 30 stream may be had,which may be useful in hosing oi, a sidewalk or similar surface. TheWhole united structure of outer housing Id, innerA sleeve I5, partitionI6, cap I9, and adjusting sleeve 20, are rmly, though turnably, 35

held to the cup-shaped extension I by means of the screw-pin 23. i v

. The cap I9 may be crimped directly to andv over the edge ofthe housingI4 though a separate clamping ring 24 has been indicated. 40

This clamping ringl may even be shaped so as to'facilitate an exchangingof caps with different,

` larger or smaller apertured, spraying means.

Each of the projections, or outwardly extending edge portions 26, arepreferably shaped tovform 55 wedge-like means when seen from the side,as illustrated in Fig. 7.

The clamping ring, suitable for such an edge, takes eventually the formillustrated in Figs. 8 and 9; While the outer edge may preferably be inform of a smooth fiange 21 the opposite edge would naturally have tohave notches to correspond with the notches in the edge of the housing Mand also Wedgelike as indicated at 28 in Fig. 9.

To assure a quick and positive proper location of the turning positionof the housing on the cup-shaped extension, stops are provided on therear base portion I0 as Well as on the housing, or united structure, asindicated in Fig. 3, one stop 29 being o-n one part, while the otherstop 30 is on the other part, whereby the housing may be quickly andpositively brought to aligning position for discharging through eitherthe wider spray or the central single stream discharge; though, ofcourse, the previously referred to communications may be opened more orless without turning to the full-discharge stop positions.

The cup-shaped extension is not necessarily of the cylindrical formillustrated in Fig. 2, as will be understood from the illustration inFig. 5, in which this extension Ila is conical, and the sleeve portionshaped.

From the above, and from the illustrations, it should be understood thatany discharge from a connected hose can be shut off entirely by reasonof the fact that the openings l1 and I8 can be. far enough apart thatneither will be in aligning position.

Having thus described my invention, I claim:

In a hose sprinklerhead of the type described, a base having a portionto screw to the end of a hose and having a cup-shaped extension withdistinct discharge openings, a head having a portion to turnably fit onsaid extension with an outer housing and a partition between the housingand the portion forming distinct compartments, a wide-spray cap over theouter compartv ment, a central narrow-spray means in operative relationto the inner compartment, adjusting means for the narrow-spray meanswhereby the narrow spray may be adjusted between a singlestream fulldischarge and a fine spray, and the head having distinct communicatingopenings for the compartments to individually align with the openings inthe extension.
